Chinese spacecraft Tiangong-1 is tumbling out of orbit above Earth, and is expected to re-enter Earth's atmosphere uncontrolled this weekend, the European Space Agency said. The spacecraft will re-enter Earth's atmosphere between Saturday morning and Monday morning. Tiangong-1 was at orbit roughly 200 miles above Earth after it launched in 2011. Slight atmospheric drag causes spacecrafts to decay in their altitude. As a result, spacecrafts have to conduct regular ‘reboost maneuvers’ to maintain their orbit, the European Space Agency said. Since December 2015, controllers on the ground have been unable to perform such maneuvers to keep it in orbit. Originally the plan was to control its re-entry to direct the craft into an unpopulated section of Earth. With no one able to control the spacecraft, it will tumble to the Earth somewhere between 43 degrees north and 43 south latitude. While that means much of the United States could be impacted by the falling spacecraft the size of a school bus, the European Space Agency projects that much, but not all, of the craft will break apart in the Earth's atmosphere. “Owing to the geometry of the station’s orbit, we can already exclude the possibility that any fragments will fall over any spot further north than 43oN or further south than 43oS,” says Holger Krag, Head of ESA’s Space Debris Office.The European Space Agency will be providing updates as it better projects when and where the spacecraft tumbles out of space and back to Earth.  1547

CHULA VISTA, Calif. (KGTV) -- Pastor Art Hodges stood on the steps of Chula Vista City Hall Wednesday, surrounded by about 50 people of faith. "Hear our prayer. Forgive our sin," Hodges said during the group prayer.The people were rallying against a program that calls for drag queens to read to children. Drag Queen Story Hour is scheduled to start Tuesday at the Chula Vista Civic Center Library. At the rally, those opposing the program said it would harm a child's growth and development. They also demanded public hearings."If there are parents that want drag queens to come read books to their children, they have that right. They're the parents, we're not protesting their right," said Hodges. "But they should do that privately, on their own time, in their own place, on their own dollar."Supporters say the program promotes tolerance and acceptance. Chula Vista Mayor Mary Salas called it "preposterous" to have a City Council vote for a one-hour reading program, which she said would not be canceled. "The City of Chula Vista is proud to celebrate the diversity of our community in all of our programs," Salas said in a statement. "The purpose of this event is to encourage children to use their imagination and creativity and most importantly to read."The tone of Wednesday's rally was much different than one held last week, in which tempers flared from the start. This time, only a handful of Drag Queen Story Hour supporters watched the rally from the side. Supporter Shelley Rudd, a retired teacher, said the drag queen reading program benefits children. "I think that it really helps those children who may be questioning, an opportunity to see that there are options and that it's okay," Rudd said. Last week, a different rally organized by a group called Mass Resistance got heated, with police stepping between both sides on two separate occasions. The Southern Poverty Law Center designated Mass Resistance an anti-LGBT hate group. Its California leader attended Wednesday's rally but did not speak at the podium. 2042

The city and the port authority will pay for a combined 0+ million. Port commissioners said it is a large investment for an even larger long-term reward. "As far as what we'll get back, we will see an immediate impact by the fact that it's going to create 10,000 construction jobs, and it's going to put about a billion dollars in the local and regional economy," Moore said. RELATED: South Bay residents get an idea of massive bayfront developmentIn August of 2017, the City gave residents a better idea of what the Bayfront will look like in the next 20 years.The anchor for the Bayfront is set to be a .1 billion resort hotel and convention center that the city says will be built by Houston-based RIDA Development.The current Chula Vista RV Park will also move roughly a mile away to make room for construction.
